Comment:

 For context, the preceding text is

 ------

   Create a file mylist.txt with all the files you want to have
 concatenated in the following form (lines starting with a # are ignored):

   {{{
   # this is a comment
   file '/path/to/file1.wav'
   file '/path/to/file2.wav'
   file '/path/to/file3.wav'
   }}}

   Note that these can be either relative or absolute paths. Then you can
 stream copy or re-encode your files:

 {{{
 ffmpeg -f concat -safe 0 -i mylist.txt -c copy output.wav
 }}}

   The -safe 0 above is not required if the paths are relative.

 ------

 So 'paths' refers to the file paths specified in the concat text file, as
 signified by the specimen `/path/to/file1.wav`. With `-safe 1`, all file
 paths must be deemed safe.

 Here's the requirement for filename safety, as given in the
 [http://ffmpeg.org/ffmpeg-formats.html#Options docs]:

    If set to 1, reject unsafe file paths. A file path is considered safe
 if it does not contain a protocol specification and is relative and all
 components only contain characters from the portable character set
 (letters, digits, period, underscore and hyphen) and have no period at the
 beginning of a component.
